For those with sloth-like gardener tendencies, the lazy ones who, let's say, never bothered to rake the leaves in the fall or trim errant branches on their Japanese maples, this weekend in Portland offers a chance to catch up.

The National Weather Service is calling for mostly cloudy skies and slight chances of rain with cool temperatures on Friday, Saturday and Sunday. We like to think of it as weeding weather.

Friday starts with patchy morning fog turning to clouds and a 20-percent chance of rain. Look for highs up to 50 degrees and northwest winds up to 10 miles per hour.

Friday night's forecast is for continuing clouds and patchy fog after midnight, and lows around 30.

Partly sunny skies are expected on Saturday, after patchy morning fog. Highs could again reach 50. Come evening, the clouds roll back in. There's a 20-percent chance of rain, plus patchy fog after midnight and lows down to 30.

Sunday's forecast begins with patchy morning fog followed by mostly cloudy skies and, once again, a 20-percent chance of rain. Highs should climb to about 45.

As the weekend wraps, the chance of rain increases to 40 percent Sunday night, when lows drop to 35.
